🚨 Serious Problems (6)
Root Rot
Root rot is a serious fungal disease that affects the root system of plants, causing them to decay and die. It is primarily caused by overwatering, poor drainage, or soil-borne fungi such as Pythium, Phytophthora, Rhizoctonia, and Fusarium. The disease thrives in waterlogged conditions where roots are deprived of oxygen, making them susceptible to fungal infection.
Symptoms:
Wilting leaves despite moist soil • Yellowing or browning of leaves • Stunted growth and poor vigor
⚡ Quick Fixes:
Emergency unpotting: Remove plant immediately from wet soil. Speed is critical....
Gray Mold (Botrytis Blight)
Gray mold, caused by the fungus Botrytis cinerea, is one of the most common fungal diseases in plants. It affects over 200 plant species, including ornamentals, vegetables, fruits, and houseplants. The disease thrives in cool, humid conditions with poor air circulation, causing grayish spots and soft rot on infected tissues.
Symptoms:
Grayish colored soft, mushy spots on leaves, stems, and flowers • Gray fuzzy coating of fungal spores, especially in high humidity • Brown to gray circular spots on leaves and petals
⚡ Quick Fixes:
Remove and dispose of all visibly infected parts: Remove and dispose of all visibly infected parts...
Pythium Root Rot
Pythium root rot is a serious fungal disease caused by various Pythium species including P. aphanidermatum, P. ultimum, and P. irregulare. These water molds are present in practically all cultivated soils and attack plant roots under wet conditions, causing rapid wet rot that can extend into the stem. The disease is favored by poor drainage, overwatering, and specific temperatures depending on the species.
Symptoms:
Dark brown to black wet rot of roots • Roots soften and disintegrate easily • Outer cortical tissue pulls off easily exposing vascular strand
⚡ Quick Fixes:
Step 1: ...
Phytophthora Root Rot
Disease caused by fungus-like organisms (oomycetes) that live in soil and can survive for years. It affects roots, stem, and crown of plants, being especially severe in waterlogged or poorly drained soils. It is the second most common cause of root rot in trees and shrubs.
Symptoms:
Leaf wilting despite moist soil • Yellowing or discolored foliage (dull green, yellow, red, purplish) • Sparse foliage and progressive branch dieback
⚡ Quick Fixes:
Expose plant base by removing soil to main roots: Allow area to dry completely...
Spider Mites
Spider mites are tiny arachnids (less than 1/20 inch long) related to spiders and ticks that feed on plant sap. They thrive in hot, dry conditions and can cause significant damage to ornamental and vegetable plants. During severe infestations, crop losses can reach 14% or higher as these pests disrupt vital plant processes including photosynthesis, carbon dioxide absorption, and transpiration.
Symptoms:
Pale discoloration spots on leaves • Fine silk webbing covering leaves and stems • Tiny yellow or white speckles on leaf surface (stippling)
⚡ Quick Fixes:
Step 1: Immediately spray all affected plants with rubbing alcohol (70% isopropyl) diluted 1:1 with water...
Mealybugs
Mealybugs are small, soft-bodied insects covered with a white, waxy, cottony material. They are common pests of houseplants and outdoor plants in mild climates. These sap-sucking insects feed on plant tissue, causing damage, stunted growth, and can lead to plant death if left untreated. They produce sticky honeydew which attracts sooty mold.
Symptoms:
White cottony masses on leaves, stems, or fruit • Small pink or white soft-bodied insects (1/20 to 1/5 inch) • Sticky honeydew secretions on plant surfaces
⚡ Quick Fixes:
Step 1: Immediately spray visible mealybugs with 70% isopropyl alcohol for instant kill on contact...
